Worked on the trezor/trezor-firmware repository to enhance release automation and testing workflows over a two-month period. Developed features to support Tropic-capable emulator builds, enabling model-specific releases for both x86 and arm64 architectures. Centralized the Tropic model list and organized emulator outputs into dedicated subdirectories, improving maintainability and consistency. Expanded the upgrade test suite to cover additional models and refined environment provisioning, while also updating documentation to clarify setup and execution steps for upgrade tests. Leveraged skills in CI/CD, GitHub Actions, and Python, with supporting work in Shell and YAML, focusing on workflow reliability and developer experience.
